BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a dehumidifying device, and more particularly to a dehumidifying device which has an effect of filtering water therein.

2. Description of Related Art

With reference to FIG. 4, a first conventional dehumidifying device (4), which can filter water derived from redundant moisture in the air, has a hollow body (40). An air inlet (41) and an air outlet (42) are respectively provided on two opposed sides of the conventional dehumidifying device (4). An airflow passage (not numbered), which is formed between the air inlet (41) and the air outlet (42), has a heat exchanger (43) and a blower (44) therein. The heat exchanger (43) is composed of a steamer (431) and a condenser (432), and a compressor (47) is provided in a lower end of the hollow body (40). A water passage (45) is provided under the airflow passage, and a reservoir (46) is mounted under the water passage (45).

When the first conventional dehumidifying device (4) is operating, a refrigerant circulates in the heat exchanger (43) due to the compressor (47) and the air enters the body (40) through the air inlet (41) due to the blower (44) so that the air with moisture can perform heat exchange through the steamer (431) and the condenser (432) and reduce the temperature of the air due to the refrigerant. Hence, the moisture of the air can be condensed to drops of water and gathered in the reservoir (46) via the water passage (45). The air, the humidity in which can be decreased due to the steamer (431) absorbing the heat and the condenser (432) exporting the heat, can be exhausted via the air outlet (42).

With reference to FIG. 5, another preferred embodiment of a second conventional dehumidifying device (5) comprises a hollow body (50). An air inlet (51) and an air outlet (52) are respectively provided on two sides of the body (50) and an airflow passage is formed between the air inlet (51) and the outlet (52). A heat exchanger (53), which comprises a radiator (531), a refrigeration means (532), and a condenser (533), and a blower (not numbered) are provided in the airflow passage. The radiator (531) is composed of heat sinking slats, and the refrigeration means (532) is composed of chilling chips. The heat exchanger (53), which can be controlled by a circuit board (not numbered), has a water passage (55) thereunder. A reservoir (56) is provided under an out port of the water passage (55). The dehumidifying device (5) is an electrical dehumidifying device, the heat exchanger (53) of which is controlled by the circuit board so that the moisture of the air can be condensed to drops of water thereby dripping into the water passage (55) and accumulating in the reservoir (56).

However, the collected water of the first and second conventional dehumidifying devices (4, 5) is not appropriate for people to drink or use because it may have impurities therein. Hence, the collected water is only used to irrigate plants, clean floors thereby not maximizing the water resource.

Therefore, the invention provides a dehumidifying device to mitigate or obviate the aforementioned problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIG. 1, a first preferred embodiment of a dehumidifying device (1) has a hollow body (10), and an air inlet (11) and an air outlet (12) are respectively defined in two sides of the hollow body (10). An airflow passage, which is formed between the air inlet (11) and the air outlet (12), is provided with a heat exchanger (13) and a blower (14). A compressor (18) is provided in a lower end of the hollow body (10) and a water passage (15) is provided under the heat exchanger (13). A reservoir (17) for gathering water is mounted under a water outlet of the water passage (15).

The heat exchanger (13) is composed of a steamer (131) and a condenser (132) which are both connected to the compressor (18) through a refrigeration tube thereby forming a circulation passage so that the temperature of the air can fall due to the heat exchanger (13) and the moisture in the air can be condensed to drops of water and be collected by the water passage (15).

A filter (16) is provided between the water outlet of the water passage (15) and the reservoir (17) so that the water which is collected by the water passage (15) can be filtered through the filter (16) and stored in the reservoir (17). Therefore, the water which is purified by the filter (16) can be drunk and used in many useful ways.

With reference to FIG. 2, a second preferred embodiment of the dehumidifying device (2) has a hollow body (20) with an air inlet (21) and an air outlet (22) respectively defined in two sides of the hollow body (20). An airflow passage, which is formed between the air inlet (21) and the air outlet (22), is provided with a heat exchanger (23) and a blower (24). The heat exchanger (23) includes a radiator (231), a refrigeration means (232) and a condenser (233). The heat exchanger (23) can be controlled by the circuit board and a water passage (25) is provided under the heat exchanger (23). A reservoir (26) is provided under a water outlet of the water passage (25). In the second preferred embodiment of the dehumidifying device (2), an electrical dehumidifying device turns the moisture of the air into water falls into the water passage (25) due to the circuit board controlling the heat exchanger (23).

A filter (30) is provided between the water outlet of the water passage (25) and the reservoir (26) so that the water which is collected by the water passage (25) can be filtered through the filter (30) and then stored in the reservoir (26). Therefore, the water which is purified by the filter (30) can be drunk and used in many useful ways.

The filter (16, 30) can purify the water with filtering layers of active carbon materials or with filtering layers of multiple filter beds, filter films and active carbon materials. Furthermore, with a theory of reverse osmosis, the filter (16, 30) comprises multiple reverse osmose films and a motor which can pump the water thereby forcing it through the converse infiltrating films and effective insulating mineral substance such as calcium, magnesium, potassium, aluminum, and heavy metals to soften the water. The filter (16, 30) can also include filtering layers with the active carbon materials and a filtering core which can exchange ions into resin. Additionally, the filter (16, 30) has filter layers with a filtering core with carbon ions which can filter impurities and germs, and can electrolyte the water into alkali ion water with the active carbon materials. Or, an ultraviolet radiation means can be provided on the filter (16, 30) to kill the germs in the water.

With reference to FIG. 3, a solar energy plate (27) is provided on a top end of the dehumidifying device (1, 2) thereby absorbing the solar energy so that the solar energy can be transformed to electrical energy to operate the blower (24) and save electricity.
